FIELD

The exemplary embodiments relate generally to a modular ice barrel that is shipped in component form and minimizes shipping volume. Once the ice barrel is delivered to the final destination, individuals can expediently assemble the components. As a result of the reduced volume and assembly capability, shipping and transportation costs are minimized and greater amounts of ice barrels delivered in a single shipment can be increased.

BACKGROUND

Ice barrels can be shipped fully assembled to the point of use from a distant location. This can result in empty space in the interior cavity of the barrel to be shipped along with the fully assembled barrel. An example shipping container may be roughly 24 inches by 24 inches by 24 inches with a total volume capacity of roughly 13,824 cubic inches. Assembled ice barrels can exceed the volume capacity of a standard shipping container. As a result of wasted space and size limitations, the cost of shipping a fully assembled barrel may be greater than the cost of the barrel itself. Although injection molding can be used in conjunction with the examples disclosed herein, injection molded components may add to the weight of the barrel adding to the cost of shipment. Also when turning over a heavier weight barrel to empty water and ice from the interior cavity, in certain instances may lead to injury due to the weight of the barrel.

SUMMARY

An example portable ice barrel may include one or more of an exterior barrel wall, an interior barrel wall, and insulative layer positioned in between the exterior barrel wall and the interior barrel wall. In one example, the interior barrel wall can comprise an expandable bladder made of flexible material and the expandable bladder can have an open end, a closed end, and can be adapted to expand from a collapsed position into an expanded position. In the collapsed position, the bladder can be folded into a compact position to reduce the volume of the interior of the bladder to minimize shipping volume. Other components of the example portable ice barrel such as the lid, top rim, bottom rim, and base may also incorporate living hinges to allow the components to be collapsed further reducing the shipping volume.

In another example, a portable ice barrel can include a plurality of sections which can be configured to form a cylindrical insulation layer. The cylindrical insulation layer can form an opening and an inner liner can extend into the opening of the cylindrical insulation layer to form an interior barrel cavity for receiving ice and the desired contents. In one example, the plurality of sections can be disassembled to minimize the shipping volume.

In yet another example, a portable ice barrel may include one or more of an exterior barrel wall, an interior barrel wall, and insulative layer positioned in between the exterior barrel wall and the interior barrel wall. The interior barrel wall can comprise an expandable bladder made of flexible material and the expandable bladder can have an open end, a closed end, and can be adapted to expand from a collapsed position into an expanded position. In the collapsed position, the bladder can be folded into a compact position to reduce the volume of the interior of the bladder to minimize shipping volume. After assembly of the individual components, insulative material can be injected into a gap between the exterior wall inside surface and the bladder exterior surface to form an insulative layer there between.

Referring to FIGS. 1-8, in an embodiment, a portable ice barrel 1 can include an exterior barrel wall 2, an interior barrel wall 3, and insulative material 4 positioned in between the exterior barrel wall 2 and the interior barrel wall 3. The interior barrel wall 3 can be an expandable bladder 3 made of a flexible material. Example flexible materials include but are not limited to flexible plastics, including flexible polyvinyl chloride (PVC) films. In an embodiment, the expandable bladder may be configured to expand from a collapsed position into an expanded position. For example, in the collapsed position, the bladder can be folded into a compact position to reduce the volume of the interior of the bladder. In an example embodiment, in the collapsed position, the expandable bladder can resemble a folded bag. In addition, for example, in the expanded position, the bladder can be expanded to define a cavity of increased volume within the interior of the bladder. The expandable bladder can include an open end 5 and a closed end 6 and a bladder body segment 15 extending between the open end and the closed end. The expandable bladder can include a bladder interior surface 16 and a bladder exterior surface 17. In an embodiment, the expandable bladder can include a top drape 18 extending from a perimeter of the open end. The top drape can be configured to fold toward the exterior surface 17 proximate the open end.

In an embodiment, the expandable bladder can be configured in the expanded position within the exterior barrel wall 2 to define an interior barrel cavity 10 such that the closed end of the bladder can contain ice within the barrel cavity and the open end allows access to the barrel cavity. For example, the open end of the expandable bladder can be secured proximate to a top edge of the exterior wall 2, and the body segment of the expandable bladder can be positioned within the exterior barrel wall 2. In an example embodiment, the body segment of the expandable bladder can be cylindrical in shape when the expandable bladder is in the expanded position. In one example, an inner diameter of the body segment can be between about 18 inches to about 24 inches. In another example, a diameter of the exterior wall can be about 1 inch to about 5 inches greater than the diameter of the body segment of the expandable bladder.

In one example, the exterior barrel wall 2 includes an exterior wall outside surface 11, an exterior wall inside surface 12, an exterior wall top edge 13, and an exterior wall bottom edge 14. In an embodiment, the exterior barrel wall 2 is constructed of a semi-rigid material. Example semi-rigid materials include but are not limited to styrene, polyethylene, and vinyl. In one example, the exterior wall outside surface can be suitable for printing thereon. The exterior barrel wall can provide structural support for the interior barrel wall and/or the insulative material. In an embodiment, the exterior barrel wall can be constructed of, for example, a flexible sheet made of semi-rigid material. Example flexible sheets made of semi-rigid material include, for example, styrene sheet, polyethylene sheet, and vinyl sheet. The flexible sheet of rigid material can be flexed into the desired shape of the exterior barrel wall so that a sheet outside surface 11, sheet inside surface 12, sheet top edge 13, and sheet bottom edge 14 become the exterior wall outside surface 11, the exterior wall inside surface 12, the exterior wall top edge 13, and the exterior wall bottom edge 14 of the exterior barrel wall 2. For example, a sheet right side edge 29 can be folded over a sheet left side edge 30, or vice versa, and secured at a seam 31 to form a cylinder. Example shapes of the exterior barrel wall include cylindrical, rectangular, and oval.

In an embodiment, the insulative material can be a foam material, including for example rigid expanded polystyrene foam material. In an embodiment, the insulative material can provide structural support for the exterior barrel wall and or the interior barrel wall. In and embodiment, the insulative material can have an R-value of at least 5. In an embodiment, the insulative material can be injected into a gap 32 between the exterior wall inside surface and the bladder exterior surface to form an insulative layer 4 there between.

In an embodiment, the portable ice barrel can include a top rim 19 secured to the exterior wall top edge. In an embodiment, the top rim can include a top rim channel 20 defined within the top rim. In an embodiment, the top rim can include rim cones 21 positioned in the rim channel. In an embodiment, the rim cones can be spaced an equal distance from each other within the rim channel. In an embodiment, at least a portion of the top drape 18 of the expandable bladder is draped over a portion of the exterior wall top edge and the top rim is positioned such that the portion of the top drape and the portion of the exterior wall top edge are within the top rim channel so that the top rim channel creates a friction fit holding the top drape in position against the exterior wall top edge.

In an embodiment, the portable ice barrel can include a bottom rim 22 secured to the exterior wall bottom edge 14. In an embodiment, the bottom rim can include a bottom rim channel 23 defined within the bottom rim. In an embodiment, the bottom rim can include rim cones 21 positioned in the bottom rim channel. In an embodiment, the rim cones can be spaced an equal distance from each other within the bottom rim channel. In an embodiment, at least a portion of the exterior wall bottom edge is positioned within the bottom rim channel to create a friction fit between the bottom rim and the exterior wall bottom edge to hold the bottom rim in position against the exterior barrel wall.

In an embodiment, the expandable bladder includes a drain pipe 7 secured proximate the closed end of the bladder 3. The drain pipe can include a proximal end 8 and a distal end 9. The drain pipe proximal end can be secured to the closed end of the expandable bladder. In an embodiment, the drain pipe can be constructed of a plastic material and the proximal end 8 can be secured to the expandable bladder by a suitable plastic welding technique. For example, the drain pipe can be constructed of rigid PVC and welded to the bladder by high frequency welding, including radio frequency heat sealing. In an embodiment, the drain pipe is configured such that the drain pipe distal end extends through the exterior barrel wall. In an embodiment, a drain pipe valve can be secured to the distal end of the drain pipe. Example drain pipe valves can include a one-way check valve or a ball valve.

In an embodiment, the portable ice barrel includes a lid 24 configured to removably cover the interior barrel cavity. In an embodiment, the lid can include a lid hinge 27 and lid handle 28. In an embodiment, the lid handle is a hold defined in the lid 27. The lid can be constructed of, for example, clarified polypropylene or PEGT. In an embodiment, the portable ice barrel can include a sign holder 25 and a sign holder extrusion 26 configured to hold a sign. In an embodiment, as depicted in FIG. 7, the sign holder extrusion 26 is in the form of a clamp. In an embodiment, the portable ice barrel includes a barrel base and casters (not shown). In an embodiment, the barrel base is in the form of a tray on which the bottom of the portable ice barrel can be placed. The barrel base can be the same shape as the portable ice barrel. In an embodiment, casters are secured to the underside of the barrel base to facilitate moving the portable ice barrel by pushing the barrel while it is positioned on the barrel base. In another embodiment, the casters are secured to a collapsible barrel cooler bottom rim with a living hinge by a plurality of support tubes.

The portable ice barrel of the instant disclosure can be assembled according to various methods including steps and components disclosed herein. In an embodiment, a barrel form 31 is used to assemble the portable ice barrel of the current disclosure. In an embodiment, the barrel form 31 is shaped in the shape desired for the interior barrel cavity 10. In an embodiment, the expandable bladder can take the shape of the barrel form 31 when the bladder is expanded and positioned over the form 31 to cover the form 31 with the interior surface of the bladder. In an embodiment, the open end of the expandable bladder is expanded and placed over the barrel form as depicted in FIG. 8A. In an embodiment, the bladder is pulled down over the form so that the bladder open end is positioned proximate the form open end 33 and the bladder closed end is positioned proximate the form closed end 34, such as shown by example in FIG. 8C.

In an embodiment, a top rim is positioned over the barrel form 31 so that the top rim encircles the form 31. In another embodiment, a collapsible top rim with a living hinge is positioned over a collapsible heat stake plate with a living hinge. In an embodiment, the bladder top drape 18 is positioned in the top rim channel 20 so that a portion of the top drape covers a portion of the inside surface of the top rim channel 20, such as shown by example in FIG. 8C. In an embodiment, an exterior barrel wall 2 can be positioned around the expandable bladder 3 covering the barrel form 31 so that a gap 32 is defined in between an inside surface 12 of the exterior barrel and the bladder exterior surface 17. In an embodiment, the exterior barrel wall can be formed by flexing and welding a flexible sheet as described above before the exterior barrel wall is positioned around the interior barrel wall. In addition, in an embodiment, the logos and/or graphics can be printed on the outside surface of the sheet prior to forming the sheet into the exterior barrel wall. In an embodiment, the exterior wall top edge 13 is positioned in the top rim channel and in contact with a portion of the top drape of the expandable bladder which is also positioned in the top rim channel so as to form a friction fit seal between the top drape 18 and exterior wall top edge 13. In an embodiment, an adhesive can be used to adhere the top drape of the bladder to the top rim channel and/or adhere the exterior wall top edge to the top drape of the expandable bladder. In an embodiment, the distal end of the drain pipe can be positioned to extend through a hole defined in the exterior wall. In an embodiment, a bottom rim can be positioned over the exterior wall bottom edge, such as shown by example in FIG. 8C. In an embodiment, the dimensions of the exterior barrel wall 2 and the interior barrel wall 3 can be configured so that the gap 32 defined in between the exterior wall inside surface 12 and the bladder exterior surface 17 can be about 1 inch to about 5 inches. In an embodiment, insulative material is inserted into the gap through the bottom of the barrel to form the insulative layer 4. In an embodiment, the insulative layer covers the bladder body segment. In an embodiment, the insulative layer covers the bladder exterior surface at the closed end of the bladder. In an embodiment, once the insulative layer is in place or cures, the barrel form can be removed to expose interior barrel cavity. In an embodiment, the portable ice barrel is rotated from an upside-down position shown in FIG. 8C into an upright position shown in FIG. 8D before the barrel form is removed from the interior barrel cavity. In an embodiment, the lid, sign holder, and sign extrusion can be secured to the top rim. In an embodiment, casters can be secured to the underside of a barrel base and the portable ice barrel can be positioned onto the barrel base. In another embodiment, the casters are secured to a collapsible barrel cooler bottom rim with a living hinge by a plurality of support tubes.

FIGS. 9-14E depict another example portable ice barrel 101. The portable ice barrel 101 can include similar components as the example depicted in FIGS. 1-8. These components are labeled with like reference numerals in the accompanying drawings but use 100 series reference numerals. In the example shown in FIGS. 9-14F, instead of using insulative material 4, a series of barrel sections or baffles 104, as shown in FIG. 11, are used to provide insulation to the contents of the portable ice barrel 101. In another example, as shown in FIG. 15, an outer and inner layer form a gap of air that provides insulation to the contents of the portable ice barrel 101. FIG. 9 shows a top perspective view of the example portable ice barrel 101, and FIG. 10 shows a side perspective view. The exterior of the portable ice barrel 101 generally includes a top wall 135, a lid 124, a drain pipe 107, an exterior barrel wall 103, and a bottom rim 122 which can be configured to receive a series of wheels 137. The exterior barrel wall 103 can be formed as a graphic panel and can include any name, logo, or symbol depending on the contents and desired advertising. The top wall 135 can have a partial rim 119 and can be configured to receive a lid 124. The lid 124 provides an opening into the interior barrel cavity 110 formed in the portable ice barrel 101, and can be hingedly connected to the top wall 135 by hinge 127. The lid 124 may also include a handle 128, which can be in the form of a projection for opening the lid 124. Additionally the top wall 135 can be formed with a notch 128 a for receiving the handle 128 of the lid 124. In one example, the lid 124 can be provided with a living hinge (not shown) that separates the lid 124 into two sections such that the lid 124 can be folded into a smaller configuration for easy and compact shipment.

FIG. 11 depicts an exploded perspective view of the portable ice barrel 101 showing both the exterior and interior components of the portable ice barrel 101. In addition to the exterior components described above, the example portable ice barrel 101 can include an insulation layer 160 formed of barrel sections 104, a bladder or liner 102, and a base assembly 136 Like in the example shown in FIGS. 1-8, the liner 102 forms an interior barrel cavity 110 for receiving contents, such as ice and any desired products.

As shown in FIG. 11, the barrel sections 104 are configured to fit under the top wall 135 and between the exterior barrel wall and the liner 102. The barrel sections 104 can each be formed identically. As will be described in further detail below, the barrel sections 104 form the cylindrical insulation layer 160 by trapping air between the liner 102 and the exterior barrel wall 103.

In this example, six barrel sections 104 can be provided. In one example, each of the barrel sections 104 can comprise 30 degrees of the cylinder forming the portable ice barrel 101. However, any number of sections can be provided for the desired insulation and manufacturability. The barrel sections 104 can be provided with a slight curvature such that they form a cylinder when assembled in the portable ice barrel 101. The curvature can be slight enough such that the barrel sections 104 can be shipped in a mostly flat configuration.

FIGS. 12A-12D depict perspective side and top views of the portable ice barrel 101 before attachment of the exterior barrier wall 103 onto the portable ice barrel 101. As shown in FIGS. 11-12D, the outermost surfaces of the barrel sections 104 can be formed with a series of fins 142. When the portable ice barrel 101 is assembled, the fins 142 extend from an outermost wall forming the barrel sections 104 to the exterior barrier wall 103. The fins 142 are configured to trap air between the exterior barrier wall 103 and the liner 102. Air is generally a good thermal insulator, and helps to slow outside or ambient temperatures from melting the ice or warming the contents stored in the interior barrel cavity 110. Alternatively, the fins 142 trap air to help prevent heat from escaping the interior barrel cavity 110 should it be desired to store warm contents. In this way, the barrel sections 104 provide thermal insulation to the liner 102 and the contents stored therein.

FIGS. 13A-13F show partially formed barrel sections 104 to illustrate an example connection method for securing the barrel sections 104 together. As shown in FIGS. 13A-13F, the barrel sections 104 can be provided with tongue and groove type connections 148. In particular, each side of the barrel sections 104 can be provided with either a tongue 149 or a groove 150. The tongue 149 can be formed of two L-shaped legs 151 that project outwardly. The L-shaped legs 151 of the tongue 149 can be formed of a thin plastic material such that the legs have a degree of resiliency. Additionally, the groove can be defined by two facing L-shaped legs 152 and a resilient V-shaped projection 153. The legs 151 can be configured to resiliently extend into the groove 150 such that when the legs 151 of the tongue 149 are placed into contact with the groove 150, the L-shaped legs 151 contact the L-shaped legs 152 causing the L-shaped legs 151 to resiliently bias against the L-shaped legs 152. As shown in FIG. 13D to secure the barrel sections 140 together the tongue 149 is aligned with the groove 150 such that the legs 151 extend into the groove 150. Once the L-shaped legs 151 are placed into contact with the L-shaped legs 152, the barrel sections 140 are held together securely in both a vertical and horizontal direction. It is contemplated that the barrel sections 104 can be secured together using any known connection method such as removable fasteners, adhesives, snap-fit, etc.

As shown in FIGS. 13F-13I, once the barrel sections 104 are secured together, the L-shaped legs 151, the L-shaped legs 152, and the V-shaped projection 153 also define a recess for receiving a push-in clip 146 located on a top wall section to secure the top wall 135 to the top of the barrel sections 104. As depicted in FIG. 13F, the push-in clip 146 can be a Christmas tree-type clip. As shown in FIG. 13F, the clips 146 are installed through a hole 158 in the top wall 135. The clips 146 can be provided with resilient ribs, which extend along the length of the shaft of the clips 146. When the push-in clips 146 are engaged with the recess formed by the L-shaped legs 151, the L-shaped legs 152, and the V-shaped channel, the ribs located on the shaft of the clips 146 maintain the top wall 135 on the barrel sections 104. In this way, the clip 146 can be designed as a one way, press fit application such that once installed, the clips 146 are extremely difficult to remove to secure the top wall 135 to the insulation layer 160. The clips 146 can be configured to require no turning of a screw or fastener, which reduces the amount of labor to assemble the portable ice barrel.

FIGS. 14A-14E illustrate partially formed bottom sections of the barrel sections 104 to illustrate a method of connecting the bottom rim 122 to the barrel sections 104. As shown in FIGS. 14A-14E, the bottom rim 122 can be provided with a resilient locking tab 154 for securing the bottom rim 122 to the barrel sections 104 without the use of tools. In particular, the bottom rim 122 can be provided with an opening 156, which provides a cutout for the locking tab 154 to flex. The barrel sections 104 can be provided with a corresponding opening 157 for receiving the locking tab 154. Once the bottom rim 122 is placed into contact with the barrel sections 104, the locking tab 154 flexes within the opening 156 and into the corresponding opening 157 to secure the bottom rim 122 to the barrel sections 104. As shown in FIG. 14A, the locking tab 154 can be provided with a ramp 154A, which permits the locking tab to move outwardly when the bottom rim 122 is placed into contact with the barrel sections 144A-144F. Once the locking tab 154 is aligned with the opening 157 the resiliency of the tab moves the ramp 154A inwardly into the opening 157 to secure the bottom rim 122 to the barrel sections 104.

The liner 102 can be formed of a similar liner material as the example shown in FIGS. 1-8. Additionally, as shown in FIGS. 11, 15, and 13A, a series of clips 140 can be used to support the liner 102 inside the portable ice barrel 101. In particular, the liner 102 can be held in place onto the insulation layer 160 by a series of clips 140. The clips 140 can be formed U-shaped such that the clips 140 can extend over the rim of the insulation layer 160 and the liner 102 to securely hold the liner 102 into place in the portable ice barrel 101.

In one example, the top wall 135 can be formed of sections. As shown in FIGS. 13G and 13E, the sections can make up the hinge 127 for receiving the lid 124. Although not shown, the sections can also form the partial rim 119, and can be secured to the sections forming the hinge 127 using any known method. As discussed above, the top wall 135 can be secured to the barrel sections 104 using a push-in clip 146.

The base assembly 136 can be formed of a support disc 138, a series of supports 139A-139D to form a grid 139, the bottom rim 122, and wheels 137. As shown in FIG. 14C, the bottom rim 122 can be formed with a wheel mount or projection 162 for receiving the wheels 137. The supports 139A-D and grid 139 form an inexpensive, transportable, and robust foundation structure. As shown in FIG. 11 each support 139A-139D can be provided with a series of slits 143 for receiving a respective slit 143 on a corresponding support grid 139. Therefore, the grid 139 can be assembled quickly by aligning the slits 143 on the supports 139A-D. Although in this example four supports are provided, the grid 139 can be provided with two or more supports depending on the size and desired strength of the base assembly. The supports 139A-139D can be formed of any known and suitable material and in one example can be formed of a plastic material, cardboard, or other like material. In another embodiment, the base assembly can be formed by a single collapsible bottom rim that incorporates a living hinge. The casters are secured to a collapsible barrel bottom rim by a plurality of support tubes.

The drain pipe 107 can be formed similar to drain pipe 7 and extends from an interior of the portable ice barrel 101 to the exterior to provide for an outlet for ice water. In one example, the drain pipe 107 can be built into the liner 102. Additionally, one of the barrel sections 104 can be provided with a die cut hole for receiving the drain pipe 107 there through.

To assemble the portable ice barrel, the barrel sections 104 can be connected to one another using the tongue and groove connection as described above. The base 136 can then be assembled by forming the supports 139A-139D into a grid 139. The disc 138 and the support grid 139 can then be placed inside the insulation layer 160 formed by the barrel sections 140.

FIGS. 17A-17O depict another example insulating device or container 301, where like reference numerals refer to the same or similar elements in all of the various views but include 300 series reference numerals. The example shown in FIGS. 17A-17F is similar to the example shown in FIGS. 15A-15F; however, this example implements a series of structural wires or rods 305 for structural support of the insulating device 301 in addition to other variations that will be discussed below. The example insulating device 301 can be configured to be a portable and collapsible cooler similar to the above examples. In one example, the insulating device 301 can fit into a 20 in. by 6 in. by 40 in. box for shipment, and the insulating device 301 can have volumes similar to the volumes discussed in relation to the other examples discussed herein. The example insulating device 301 can include a base 336, an exterior wall 303, an interior bladder or liner 302, a liner rim 306 for securing and retaining the liner 302, a lid 324, an exterior liner 304, and a top rim 335.

In this example, the base 336 can be formed of a bottom plate 322, casters 337 having wheels, and supports 308. FIGS. 17B-17D show further detail of the bottom plate 322, where FIG. 17B is a top perspective view, FIG. 17C is a side view, and FIG. 17D is a bottom perspective view. As shown in FIG. 17B, the bottom plate 322 can include a series of openings 319 for receiving supports 308, which can be in the form of tubes or cylinders. The supports 308 are configured to support the bottom of the inner liner 302 when the inner liner 302 is filed, for example, with ice, beverages, or other contents. The supports 308 can thus transfer all of the weight of the inner liner 302 contents to the bottom plate 322 of the insulating device 301. In alternative examples, a single support can be provided or the support can be in the form of a frame that is configured to support the weight of ice and other contents that will be stored in the insulating device 301. The supports may also be telescopically arranged on the base, such that the supports are configured to extend outward during the assembly of the insulating device 301.

The bottom plate 322 may also include one or more indicators 321 to indicate to the user the orientation of the inner liner 302, the exterior liner 304, and the rods 305. For example, as shown in FIG. 17B, arrows can direct the user to the back of the insulating device 301 and notches or inserts 366 located in the bottom plate 322 for assembling the insulating device 301. The series of inserts or notches 366 on the bottom plate 322 are configured to receive the rods 305. In particular, the inserts 366 are configured to receive the ends 380 a, 380 b of the wire rods 305. The inserts 366 can also include a ramp surface that is configured to engage the end of the wire rod 305. The ramp surface is provided with an angled surface such that when the end of the wire rod 305 engages the notch, the rod 305 can be pushed along the angled surface and held into place by the ramp surface. The rods 305 may also be held into place on the bottom plate 322 with slots. Other connections between the rods 305 and the bottom plate 322 are also contemplated. For example, one or more of a threaded, ball and socket, or bayonet connections are also contemplated.

Additionally, FIG. 17C shows a side view of the bottom plate 322. Because the exterior wall 303 is placed onto the insulating device last, the exterior liner 304 may interfere with the placement of the exterior wall 303 over the rim 335. Specifically, the exterior liner 304 may prevent the user from positioning the exterior wall 303 at a sufficient angle with respect to the rim 335 to allow the exterior wall 303 to be placed within the rim. The bottom plate 322 can, therefore, be provided with an angled or beveled rim 355, which helps assist in the assembly of the exterior wall 303. In particular, the angled rim 355 provides a higher point to which the exterior wall 303 can be placed over the bottom plate 322 first and then subsequently flexed around the lower points of the angled portion of the rim 355. When the exterior wall 303 is installed over the exterior liner 304, the bottom portion of the exterior wall 303 can be positioned within the bottom plate 322 over the angled rim 355. Once the exterior wall 303 is installed, the angled rim 355 holds the exterior wall 303 into place.

The casters 337 are configured to attach to the bottom plate 322 via an interference fit or snap fit connection to allow for an easy assembly. Specifically, as shown in FIG. 17D, which is a bottom view of the base plate 322, holes 359 can be provided in the bottom plate 322 for receiving the casters 337. The holes 359 can be dimensioned such that the casters 337 fit within the holes 359 by way of an interference fit. However, other types of connection methods are contemplated for securing the casters 337 to the bottom plate 322. For example, the casters could be connected to the bottom plate 322 by a threaded connection, a ball and socket connection, or a bayonet connection as well as other types of known connections in the art.

The exterior wall 303 is shown in FIG. 17E. The exterior wall 303 can be formed in as a rectangular sheet of material that is configured to roll up into a cylinder, by, for example, adding an adhesive to the strip or area 365 or by way of mechanical fastener and securing the area 365 to the opposite end. In this way, the exterior wall 303 can be formed of a flexible material such that the exterior wall 303 can be easy rolled up into a cylinder shape and can be flexed and collapsed into a smaller volume container for shipment. The exterior wall 303 can include holes 361, which when aligned, receive a drain pipe or tube 307. Additionally, the exterior wall 303 can include one or more notches 363 for aligning the exterior barrel wall with the bottom plate 322. Specifically, the notches 363 can align with the projections 366 on the bottom plate 322. The wall 303 may also include a graphic area 364 for printing any desired graphics, for example, a brand label, advertisement, price, logo, announcement, etc. It is also contemplated that the exterior wall 303 may also be extruded of a flexible material such that the exterior wall may be collapsible for shipment purposes.

FIG. 17F shows an exploded view of the inner liner 302 and the liner rim 306. As shown in FIGS. 17F and 17G, the inner liner 302 can be formed in a cylindrical shape. The inner liner 302 can be formed of a flexible plastic material that is substantially waterproof such that when ice is placed in the inner liner 302 water from the ice does not leak out of the inner liner 302. A layer of insulation material 367 can be placed on the bottom area of the inner liner 302 on the outside surface or on the inside surface of the inner liner 302 to help maintain the temperature of the inside of the inner liner 302. Additionally, insulation material can be placed at other areas along the inner liner 302 to help to maintain the temperature of the contents within the inner liner 302. The inner liner 302 may include a drain or an opening in the bottom of the inner liner 302, which can be connected to a drain pipe 307. A drain plug 384, as shown in FIG. 17F1, can be placed into the drain pipe 307 for selectively opening the drain pipe 307 to selectively control the water from the melted ice exiting the insulating device 301. The drain plug 384 can include a series of concentric rings 385 that are placed axially along a shaft of the drain plug 384. The drain plug 384 can also include a dome-shaped head 386, which includes a handle 386 a and a series of axially extending ridges 387, which are configured to engage the exterior liner 304 and the exterior wall 303 to maintain the drain plug 384 in place on the outside of the insulating device 301.

FIG. 17F also illustrates how the inner liner 302 can be connected to the liner rim 306. In one example, the inner liner 302 can be connected to the liner rim 306 by heat staking. Specifically, several flanges 370 of the inner liner 302 that project outwardly from the top of the inner liner 302 can be sandwiched between the liner rim 306 and a series of strips 371, which form a circle around the inner liner 302. The flanges 370 can also include openings 372 that receive corresponding projections 373 in the strips 371. The projections 373 of the strips 371 are received in corresponding openings 374 in the liner rim 306. Each of the projections 373 can then be heated such that they deform to connect the inner liner 302 to the liner rim 306. Other techniques are contemplated for securing the inner liner 302 to the liner rim 306. For example, fasteners may be used in the place of the projections 373 and the heat staking method. In other examples, one or more of clips, ties, or straps as well as the other examples discussed herein could be used to secure the inner liner 302 to the liner rim 306.

FIG. 17G shows a top view of the liner rim 306. The liner rim 306 also includes notches 375 for receiving and securing the ends of the wires or rods 305. Additionally, liner rim 306 includes a series of slots 376 for receiving locking tabs 369 of the top rim 335. The slots 376 may also include a corresponding pin or engagement member for maintaining the locking tabs within the slots 376. The liner rim 306 can also include a pair of knuckles 377, which receive integral pins 378 on the lid 324 to form part of a hinge for the lid 324.

The top rim 335, which may also be referred to as a bezel, is shown in FIGS. 17H and 17I. FIG. 17H shows a top view of the top rim 335, and FIG. 17I shows a partial section of the top rim 335. The top rim 335 secures around the perimeter of the top of the insulating device 301, and generally provides a cover over the liner rim 306 of the inner liner 302. As shown in FIG. 17I, the top rim 335 can be provided with a series of locking tabs 369. The locking tabs 369 can be located on the inner perimeter of the top rim 335, and the locking tabs 369 can be configured to engage the slots 376 of the top rim 335. As shown in FIG. 17J, the locking tabs 369 can include an angled portion 369 a, which can be configured to engage the underside of the slots 376 or an engagement member located within the slot 376 to help in securing the top rim 335 to the insulating device 301. In other examples, the top rim 335 can be provided with one or more of threads, pin and slot connections, ball and socket, or bayonet connections for securing the top rim 335 to the insulating device 301.

A top view of the lid 324 is shown in FIG. 17K. The lid 324 can include two pins 378 which can be received in the knuckles 377 located in the liner rim 306. In addition, the lid 324 can include an opening 379 for receiving a handle 388 such that the lid 324 can be easily lifted and rotated to retrieve the contents of the insulating device 301.

FIG. 17L shows a partial view of an example wire rod 305. The example wire rod 305 can be secured between the liner rim 306 and the bottom plate 322, and can be configured to prevent the expansion of the exterior liner 304. An example wire rod 305 can include a first coin shaped end 380 a and a second coin shaped end 380 b. The first coin shaped end 380 a is configured to fit in the notches 375 of the liner rim 306, and the second coin shaped end 380 b can be configured to fit in the notches 366 on the bottom plate 322. Therefore, due to the size of the first coin shaped end 380 a being slightly larger than the notches 375 of the liner rim and the second coin shaped end 380 b being slightly larger than the notches on the bottom plate 322, the wire rods 305 can be held in place on the insulating device 301.

The exterior liner 304 is further illustrated in FIGS. 17N and 17O. The exterior liner 304 can be formed of a rectangular sheet of material and in one example can be formed of a flexible and corrugated plastic material. Each end of the rectangular sheet can be secured together to form the exterior liner 304, for example, by an adhesive or one or more mechanical fasteners. Once assembled, the material forming the exterior liner 304 can be configured to withstand compression forces in the axial direction. The exterior liner 304 can include insulation material 381, which can be secured to the inside surface of the exterior liner 304 to provide insulation for the contents in the inner liner 302. The upper perimeter and the lower perimeter of the exterior liner 304 can be provided with location notches 383. The exterior liner 304 may also include a series of openings 389 for receiving the drain pipe 307 and plug 384 therein. It is also contemplated that the exterior liner 304 can be formed of an extruded piece of flexible material.

To assemble the insulating device 301, the casters 337 can be secured to the base plate 322, by placing the casters 337 into the holes 359 in the base plate 322. With the wheels of the casters 337 on the floor, the exterior liner 304 can then be placed onto the base plate 322. In one example, the exterior liner 304 can include indicators, e.g. numbers or letters, and the base plate 322 can include corresponding indicators 321, such that the user can properly align the exterior liner 304 with the base plate 322. The supports 308 can then be placed into the openings 319 of the base plate 322 for supporting the weight of the inner liner. The inner liner 302 can then be placed into the exterior liner 304, by aligning the drain pipe 307 with the opening 382 in the exterior liner 304. The wires or rods 305 can then be placed into the notches 375 of the liner rim 306 and then can be aligned with the inserts 366 of the base. The wires or rods 305 can then be locked into place by sliding the wires or rods 305 along each of the ramps formed on the inserts 366. The plug 384 can be placed into the drain pipe 307 to prevent the water from the ice from leaking out of the insulating device 301. The exterior wall 303 is then placed over the exterior liner 304 and then pushed into place along the bottom of the insulating device 301 such that it is pushed over the highest point of the beveled rim 355 of the base plate 322 and guided into position over the lower points of the beveled rim 355. Once the exterior wall 303 is in place, the top rim or bezel 335 can be locked into place using the locking tabs 369 to engage the slots 376 of the liner rim 306. The two pins 378 of the lid 324 can then be placed into the knuckles 377 located on the liner rim 306. The drain plug 384 can then be locked into place in the exterior liner 304 and the exterior wall 303. The insulating device 301 is also configured to be disassembled by reversing these assembly steps. For example, if it is desired to replace the graphic on the exterior wall, the exterior wall can be replaced with a new exterior wall having the new graphic.

The example collapsible containers of the instant disclosure can provide for optimized shipping, use, and assembly of the portable ice barrel according to methods disclosed herein. For example, in an embodiment, components of the portable ice barrel are shipped to an assembly location located in the vicinity of the point of use. In an embodiment, a kit which includes the expandable bladder in the collapsed position is shipped to an assembly location. In an embodiment, the kit includes the expandable bladder in the collapsed position, the top rim, the bottom rim, the lid, the barrel base, and casters. In an embodiment, the assembly location includes flexible sheets with which to form the exterior barrel wall as described above. In an embodiment, the assembly location includes facilities to print graphics on the outside surface of the sheet as described above. In an embodiment, the assembly location can include the insulative material. In an embodiment, the assembly location includes a machine and material for injecting polystyrene foam during assembly of the portable ice barrel as described above. In an embodiment, the barrel form, flexible sheets, insulative material, and/or machine for injecting insulative material can be shipped to the assembly location.

The methods of shipping, use, and assembly disclosed herein provide several advantages over conventional methods used for conventional ice barrels. For example, conventional ice barrels are often shipped fully assembled to the point of use from a distant location. This results in wasted resources from shipping air in the interior cavity of the barrel. For example, often times, the cost of shipping the fully assembled conventional barrel is greater than the cost of the barrel itself. In addition, conventional ice barrels include injection molded interior walls which add to the weight of the barrel as compared to the portable barrel with expandable bladder disclosed herein. The reduced weight of the portable ice barrel disclosed herein provides efficiencies, for example, in shipping costs and ease of use. Users of conventional barrels often turn the barrel over to empty water from the interior cavity, which can lead to injury due to the weight of the barrel. The reduced weight of the portable barrel of the instant disclosure can, for example, reduce instances of injury from turning the barrel over.

The examples discussed herein proves for a lower cost unit, which can be easy shipped, assembled and disassembled at its final location. This may help companies who purchase coolers a tremendous amount of freight cost which, depending the shipping destination could actually exceed the cost of the entire unit itself. Printing outfits around the country in major metropolitan areas can print large, wrap around graphics for the particular region. For example, a printer in Los Angeles would print graphic wraps for the Dodgers, Angels, and Kings in addition to any other regionalized need. The printer would then assemble the coolers with those wraps and ship them out locally at a lower cost.

The present disclosure and the accompanying drawings make reference to a variety of examples. The purpose served by the disclosure, however, is to provide examples of the various features and concepts related to the portable ice barrel of the instant disclosure, not to limit the scope of the disclosure to the examples.
